Membership of Subterranea Britannica is open to anyone wishing to support the society and its aims. Members receive a copy of Subterranea three times yearly and can subscribe to the members' forum which carries regular posts about underground news items and events. Membership also includes third party liability insurance which allows members to attend underground visits where this is often a requirement.

Members can help steer the society by attending an Annual General Meeting where a Committee is elected to provide day to day management and direction for Sub Brit. Members often form less formal local groups to arrange their own trips and visits. Sub Brit currently has over 1,000 members so you will almost certainly find other local members to share your interests with.

Membership is currently £28 per year, £35 for overseas members.

Subscriptions are payable on joining, and then every 12 months.

Subterranea Britannica is a company limited by guarantee. Members' liability is limited to a contribution of £1 to the company’s assets if it is wound up.
